Rick's first San Francisco rock poster was for the Jook Savages Art Show. He then produced the poster for the Human Be-In in 1967 in Golden Gate Park, advertised as the "Gathering Of Tribes", showing a guitar toting Indian on horseback. It was this event that kicked off the Summer of Love. As the Haight-Ashbury scene developed, Rick's work was in high demand. Drawing on influences as diverse as Native American culture, the Californian surf scene and of course, the burgeoning hippie movement, he incorporated beetles, skulls, surfing eyeballs, vivid colours and wild lettering into his art.
